A luminaire for a safety island or boulevard crossing

With the increasing vehicular traffic in recent years various types of signal lights for street intersections and safety islands have come into use. To distinguish these lights at a distance from ordinary street lights, red globes are used to a considerable extent. However, the base of the post is not sufficiently lighted when a red globe is used and on this account, there is danger of motorists running into it. This difficulty was overcome by the use of luminaires adopted by the South Park Commission in Chicago, and they have been used on busy intersections of Chicago boulevards with very satisfactory results.
